FOUNTAIN PEN.

Specification of Letters Patent.

Patented Mar. *7, 1922.

Application filed August 31, 1921. Serial No. 497,188.

To all 1071 0m it may concern Be it known that JAMES RING, citizen of the l mited States-of America, residing at Youngstown, in the county of Mahoning and State of Ohio, has invented certain new and useful Improvements in Fountain Pens, of which the following is a specification.

This invention relates to fountain pens which fill through the ink feeding channel, and especially to such pens as employ a rubber sac for an ink reservoir and fill by deflating the rubber sac.

Ordinarily fountain pens are constructed so as to write well only when using a specially prepared fountain pen ink.

In many lines of business it is the practice to photograph certain written instruments, such as insurance applications. etc. In order to get good results care must be taken in getting lines sufficiently dark so as to photograph well.

The principal object of my invention is to overcome the difliculty of using heavy inks, and at the same time provide a means for the relief of suction as the ink is being withdrawn from the ink sac.

Another object is to provide a simple but effective means of deflating the ink sac.

A still further object is to provide a means for adjusting the relief of suction within the ink sac.

The drawing illustrates a preferred embodiment of the invention. However, it is to be understood that in adapting the same to meeting different conditions, various changes in the form, and minor details of construction, may be resorted to without departing from the nature of the invention, as claimed and set forth in the drawings.

Figure 1 is a vertical section of the pen with the rubber reservoir in normal position.

Figure 2 is a detail view.

Figure 3 is a detail view showing side view of the deflating spring.

By referring to Figure lit will be seen that I have provided a barrel 1. Near the pen end 2 at point 3, I have provided a circular internal ledge 4. The ink sac 5 is of ordinary construction and is attached to the ink-feeding tube 6 in any desirable or ordinary way.

In order to deflate this ink sac 5, I have provided a deflating member 7 which has two deflating. springs 8. These deflating springs 8 are made of flat spring steel and have a weakened portion 9 near the center of said springs.

By referring to Figure l it will be seen that the deflating springs 8 have a decided inturned curve at the point of the weakened portions 9.

y referring to Figure 1 it will be seen I have provided an internally threaded cap 10 having a circular inner ledge 11 formed therein. The deflating member 7 is provided with a stem 12 having a head 13. In order to produce a desired friction in the turning down of this cap lO'upon the end 14. of the barrel 1, I have provided a helical spring 15, surrounding the stem 12, one end of the same resting upon the end 14, and the other against the under surface of the head 13.- This spring holds the head 13 snugly against the circular inner ledge 11.

In filling the pen or relieving the ink sac 5 from undesired suction, the cap 10 may be turned down on the external threads 16. In doing this the deflating springs 8 with ends resting on wardly and cause a desired portion of the ink sac to be deflated.

In referring to Figure 2 it will'be seen that I have provided an ordinary cap 17 to be turned on to the end 2 when the pen is not in use.

' When using heavy inks or not the flow of ink may be expedited by simply giving the cap 10 a slight downward turn.

IVhat I claim is:

In a device ofthe class described, a selffilling fountain pen, a flexible sac ink reservoir, two flat spring deflectors, weakened incurved portions on said flat spring deflectors, a circular internal ledge near the pen end of barrel of pen, an internal threaded cap, a circular internal ledge within said cap, a stem positioned on the upper end of said deflector springs. a head on said stern, a helical spring positioned around said stem, one end of same resting on the end of the barrel, the outer end in contact with the under end of Said head of stem, substantially as described for the purposes set forth.

In testimony whereof I afz'ix my signature.
